Matlab Syntax and Python Syntax

Question

I am trying to rewrite matlab code in Python. Everything was good so far, but this last equation is not coming together no matter what I do. I'm guessing it is just my poor understanding of matlab syntax. So here is the matlab equation (Un(100, 1), a(100,1), X_basis(100,100)):

uN=uN+(a(i)*X_basis(:,i));

Every numpy array has been "translated" and the values match, except uN. That is what I tried to do in Python:

for i in range(1, N+1):
    uN[i] = (a[i] * X_basis[:][i])

and I tried the uN = uN + ... version, and still, the results don't match (at all). Any idea what I am doing wrong?

Answer 1

I got it

for i in range(1, N+1):
    uNtemp[i] = np.transpose(X_basis)[:][i] * float(a[i])

for i in range(1, M+1):
    uN[i] = np.sum(np.transpose(uNtemp)[i])

It turns out Matlab basically does this piece of code. Thank you all for your comments!
